Quantitation of Ki-67 (A) and Cyclin D1 (B) immunostaining depicted in Figure 7. Statistical analysis for that percentage of positive Ki-67 cells was performed with the unpaired t-test. *P values ranging between 0.01 and 0.05 were considered significant; ***P values < 0.001 were considered highly significant. For cyclin D1, Mann–Whitney test was used. *P values ranging between 0.01 and 0.05 were considered significant; **P values ranging between 0.001 and 0.01 were considered very significant.
